On several occasions in Austin however we were treated to slo-mo replays focused between the front wheel and sidepod. This allows us to see that a vortex is also generated from the Front Wing which is ultimately targeted at the Sidepod's airflow conditioner and designed to impede the airflow from the front wheel/tyre impinging on the front of the sidepod/floor (especially during yaw).
